Grant Tribbett swept two ladies off their feet in late May when he popped the question to his girlfriend, Cassandra Reschar, and then, moments later, asked her five-year-old daughter, Adrianna, if he could be her daddy. Both ladies said, "Yes."

While the 29-year-old Tribbett proposed to Reschar with a traditional diamond engagement ring, Adrianna received a heart necklace to symbolize the permanent piece of his heart that she will always have with her.

"I knew proposing to Cassandra [meant] that I also would be committing to a lifetime of fatherhood. So what better way to ask the love of my life to marry me than to ask her beloved daughter to get the honor to be her daddy?" Tribbett told ABC News.

Reschar, 26, gave her account of the momentous event on "How He Asked," the Instagram page managed by The Knot: "After proposing to me, Grant got back down to propose to my daughter. He said, 'Adrianna can I be your daddy, to promise to love and protect you for the rest of your life?' As soon as he spoke those sweet words, I once again broke down in tears. Not the cute kind of tears either, the bawling type tears. My little heart could not take so much love! Adrianna replied, “YES!” and then screaming with joy she said, "I FINALLY GET A DADDY, MOMMY, I FINALLY GET A DADDY!'"

The heartwarming two-for-one proposal took place on a picturesque bridge inside Ritchey Woods Nature Preserve in Fishers, Ind. Tribbett had arranged for his photographer friend, Mandi Gilliland, to hide near the bridge so she could capture the moment. The resulting photos are spectacular.

The future groom recently moved from St. Louis to Westfield, Ind., to be closer to Reschar and her daughter. The couple will be hosting 125 guests at a barn wedding in December.
